TS EN 12055

TS EN 12055 is the standard for liquid chilling packages and water/water and air/water heat pumps with electrically driven compressors when they are used in cooling mode. It addresses how these systems are defined, tested and documented, and it sets out the associated requirements for rating, reporting and marking. In practice, this makes it relevant to HVAC and process-cooling equipment where comparable technical data is needed for selection and specification.

Equipment types and operating context

The standard covers electrically driven compressor-based liquid chillers and water/water or air/water heat pump arrangements. The key technical distinction is between equipment used purely for cooling and equipment used for cooling together with heat recovery. In general engineering terms, these systems move heat through a secondary liquid loop, which is why they are widely used in building services, central cooling plants and other applications where controlled heat transfer is required.

Testing, reporting and marking

This document specifies testing methods together with the rating and operational requirements summarized in the scope, and it also specifies marking requirements. That framework supports consistent product declaration and makes it easier to compare equipment from different manufacturers under a common technical basis. It is therefore as much a documentation and identification standard as it is a performance standard.
